DETECTOR-BAR.

Specification of Letters Patent.

Patented Dec. 18, 1906.

Application filed March 28, 1906. Serial No. 308.395.

.To (all whmn, it may concern-- Be it known that I, JAMES T. HAMBAY, a citizen of the United States, and a resident of the city of New York, in the State of New York, have invented certain new and useful Improvements in Detector-Bars, of which the following is a specification.

My invention relates to improvements in detector-bars, and has particular reference to detector-bar brackets, the object of the invention being to produce a device which will be more compact and easy of construction and operation than heretofore.

In the following I have described with reference to the accompanying drawings one form of device illustrating the application of my invention, the features thereof being hereinafter more particularly pointed out in the claims.

In the drawings, Figure l is a side elevation of one embodiment of my invention. Fig. 2 is a sectional view of the structure shown in Fig. 1 along the line 2 2 thereof. Fig. 3 is a sectional view of the structure shown in Fig. 1 along the line 3 3 thereof; and Fig. 4 is a detail view of the device, parts be-' ing broken away to illustrate the construction thereof more clearly.

Similar letters of reference indicate similar parts throughout the several views.

0. indicates the ordinary T-rail to which the device is adapted to be applied.

1) indicates the bracket adapted to support the operating parts. The bracket 1) comprises in part a portion 0, adapted to fit into the side of the rail, and is provided with an opening (1 to accommodate a bolt for clamping the bracket to the rail. At the lower portion of the bracket 1) are provided lugs or extensions 6 6, adapted to fit over the base of the rail and to hold the bracket in proper alinement therewith. An enlarged journalbearing f is also provided at said lower portion of bracket 1) and is preferably cast integrally therewith. A crank-arm h is mounted on said bearing f so as to freely oscillate thereon, the comparatively large bearingsurface of bearing f forming a very firm support for the crank-arm. The upper end of the crank-arm 71- is adapted to be connected with the detector-bar i by means of a suitable pivot An oil-hole 1c, protected by projecting flange Z, may also be provided for lubricating the pivot The crank-arm 7L is preferably so mounted on the bearing f that the bearing proiects slightly above the crankarm so as to form an offset or shoulder m. A back plate a is adapted to fit over the bearing f and to be seated on said shoulder m. Plate n is fastened to the bracket b by means of a bolt 0 passing through said plate and bracket at a point preferably eccentric to the axis of oscillation of the crank h, the object being to so hold the parts together that the back plate n, when fastened in place, will be held against movement. This object is further accomplished by the comparatively large area of the bearing f, against which the plate a rests. A further object for passing bolt 0 eccentrically through said bearing and plate is to advance the fulcrum-point of the crank-arm against outward thrust as near to the operating end of the crank-arm as possible, thus decreasing the strain on the bolt and increasing the ability of plate a to resist the outward thrust of the crank-arm. An oil-hole p, protected by a projecting flange 1", may be provided for the purpose of lubricating the bearing The operation of the device will be readily understood from the foregoing, the bracket I) and bearing f forming a firm support and bearing for the crank h, adapted to actuate the detector-bar L in the usual manner.

It is obvious that the details of construction as shown and described may be considerably varied without departing from the spirit of my invention, and I do not restrict myself to the details as shown and described.

What I claim, and desire to secure by Letters Patent of the United States, is

1. An apparatus of the character described including a bracket, a bearing integral therewith, a crank-arm supported directly on said bearing and means for holding the crank-arm againstoutward thrust.

2. An apparatus of the character described including a bracket, a bearing integral therewith, a crank-arm supported directly on said bearing and a plate adapted to be secured to said bearing and to hold the crank-arm against outward thrust.

3. An apparatus of the character described including a bracket, a bearing integral therewith, a crank-arm supported directly on said bearing, a plate adapted to hold the crankarm against outward thrust and a bolt adapted to secure said plate to said bearing.

4. An apparatus of the character described including a bracket, a bearing thereon, a crank-arm supported on said bearing, a plate adapted to hold the crank-arm against outbearing, means for against outward thrust and means for holdincluding-a bracket,a bearing integral therewith, a crank-arm supported directly on said olding said crank-arrn ing said bracketnnalinement with the rail.

7. An apparatusof-the character described includinga bracket, a bearing integral there- With,a crankarm supported directly on said bearing;a platesadaptedito be secured to the face ofthe bearing andtohold the crank-arm against outwardthrust.

8. An apparatus of thecharacter-described including a bracket, a bearing integral there- With, a crank-armsupported directly on said bearing in such manner that said bearing projects through said crank-arm to form a shoulder and a plate adapted to be secured on said shoulder to hold said crank-arm against out- Ward'thrust.

9. Anapparatus of the character described including a bracket, a bearing integral therewith, a crank-arm supported directly on said bearing in suchmanner that said bearingprojects'through said crank-arm to'forrn a shoulder, a 'plate adapted .to be secured to said bearing -to hold the :crank-arm against out- Ward thrust and arecess in said plate'adapted t0 fit over said shoulder.

In Witness whereof I have hereunto signed mynarne in the presence of twosubscribing Witnesses.
